我在Qt设计商中形成一种简单的形式,并试图将其装上Qt应用Im,用PySide制造,但无一uck。

这里是“pyside-uic”产生的代码:

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file  clientEditorForm.ui

        self.retranslateUi(clientEditorForm)
        QtCore.QMetaObject.connectSlotsByName(clientEditorForm)

    def retranslateUi(self, clientEditorForm):
        clientEditorForm.setWindowTitle(QtGui.QApplication.translate("clientEditorForm", "Form", None, QtGui.QApplication.UnicodeUTF8))
        self.searchLabel.setText(QtGui.QApplication.translate("clientEditorForm", "Search", None, QtGui.QApplication.UnicodeUTF8))
        self.clearButton.setText(QtGui.QApplication.translate("clientEditorForm", "Clear", None, QtGui.QApplication.UnicodeUTF8))
        self.nameLabel.setText(QtGui.QApplication.translate("clientEditorForm", "Name", None, QtGui.QApplication.UnicodeUTF8))
        self.profileButton.setText(QtGui.QApplication.translate("clientEditorForm", "Profile", None, QtGui.QApplication.UnicodeUTF8))
        self.addressLabel.setText(QtGui.QApplication.translate("clientEditorForm", "Address", None, QtGui.QApplication.UnicodeUTF8))
        self.locationLabel.setText(QtGui.QApplication.translate("clientEditorForm", "Location", None, QtGui.QApplication.UnicodeUTF8))
        self.secureLabel.setText(QtGui.QApplication.translate("clientEditorForm", "Secure", None, QtGui.QApplication.UnicodeUTF8))
        self.UUIDLabel.setText(QtGui.QApplication.translate("clientEditorForm", "UUID", None, QtGui.QApplication.UnicodeUTF8))
        self.passwordLabel.setText(QtGui.QApplication.translate("clientEditorForm", "Password", None, QtGui.QApplication.UnicodeUTF8))
        self.aliasesGroupBox.setTitle(QtGui.QApplication.translate("clientEditorForm", "Aliases", None, QtGui.QApplication.UnicodeUTF8))
        self.addButton.setText(QtGui.QApplication.translate("clientEditorForm", "Add", None, QtGui.QApplication.UnicodeUTF8))
        self.removeButton.setText(QtGui.QApplication.translate("clientEditorForm", "Remove", None, QtGui.QApplication.UnicodeUTF8))
        self.revertButton.setText(QtGui.QApplication.translate("clientEditorForm", "Revert", None, QtGui.QApplication.UnicodeUTF8))
        self.applyButton.setText(QtGui.QApplication.translate("clientEditorForm", "Apply", None, QtGui.QApplication.UnicodeUTF8))

然后我简单地提出申请:

import sys
from PySide import QtCore, QtGui

from clientEditorForm import Ui_clientEditorForm

class MyMainWindow(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(MyMainWindow, self).__init__(parent)
        self.ui = Ui_clientEditorForm()
        self.ui.setupUi(self)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = MyMainWindow()
    myapp.show()
    sys.exit(app.exec_())

然而,在我试图管理时,我得到以下信息:

QLayout: Attempting to add QLayout "" to QMainWindow "clientEditorForm", which already has a layout

以及断层错误。 http://www.rkblog.rk.edu.pl/w/p/introduction-pyqt4/ rel=“nofollow noretinger”>this tutorial,但我可以告诉我什么是错的。

最佳回答

下面是PySide与QSpacerItem级的对照。 对上述法典中的“空间轨道”实例进行评论,使其工作得当。 http://bugs. openbossa.org/show_bug.cgi?id=92”rel=“noreferer” PySide bugzilla。

问题回答

Firstly you are using PySide(Nokia) not PyQt4(Riverbank Computing), although their API s are nearly identical they are not the same project. The PySide examples are available here: git clone git://gitorious.org/pyside/pyside-examples.git

我认为,这个问题可能与你的要求有关。

super(MyMainWindow, self).__init__(parent)

审判

QtGui.QMainWindow.__init__(self, parent)

相反。

I know it seems like it is the same thing, but I ve ran into similar problems with super using PyQt4, and from what I can tell Nokia s PySide has the same troubles. It has something to do with weather the Python owns the parent or it s owned by an underlying C++ object. At least give it a 审判, it ll take less than 5 seconds!

下面是I mbeng的事例,它源自于PySide的 g。
